Description
The PT6703 is a fully integrated
13 A switching regulator housed in
a space-saving solderable package. The
PT6703 will operate from either a
3.3V or 5V input to provide a high-
performance low-voltage output that is
programmable over the range 1.1V to
1.85V. This output voltage range is
specifically suited to high performance
碌P and DSP applications that require
core supply voltages below 1.3V. The
voltage control inputs are also TTL
compatible. Additional features in-
clude output short circuit protection,
a 鈥淧ower Good鈥?output, and an over-
voltage protection (OVP) drive.
